@nixcraft Why should they throw away 50 years of C coding and adopt a new language? ISO C is a standard, and this standard is incorporated into POSIX, which all Unix systems should adhere to.

[Javad Kouhi @j_kouhi]

@ImSh4yy Postfix lookup tables.

[Javad Kouhi @j_kouhi]

@linuxopsys vi.

Because it is required by POSIX and is available on all Unix systems.

Learn once, use everywhere.

[Javad Kouhi @j_kouhi]

@nixcraft F2 to run dmenu.

[Javad Kouhi @j_kouhi]

Have you ever compared #bash and sh? The former is (mostly) #Linux-only, bloated with lots of features you never use and hard to learn, while sh is portable, standard, simple, easy to learn, and lets you do whatever you want and need!

#FreeBSD

[Javad Kouhi @j_kouhi]

@klarainc @allanjude I've been using FreeBSD since 9.0-RELEASE and never looked back.

The system is free, clean, simple, backward-compatible, and well-organised.

[Javad Kouhi @j_kouhi]

FreeBSD's base is full of interesting tools.

tcsh(1) is a great interactive shell.

fortune(6) prints tips and jokes.

procstat(1) prints lots of details about processes (usually available under /proc in linux).

script(1) records your session.

There's much more!

@someonenamedjhx @vermaden I'd set up pf, sysctls, cron jobs, log rotation, fail2ban (or blacklistd when possible), key-based ssh, dns client, and when everything is finalised, I'd save mtree's output somewhere, to use it later as a simple IDS.

@freebsdfrau It was probably worth it. Now you know them. Now you will never let them into your house, to steal something else. You paid a small price to identify a thief, it could have been more, if they didn't steal that tape measure.

Some people say that Ser is the same person behind Sadness, is there any strong evidence for that?

If you know anything about Ser, I would be thankful if you share it.

I never use #libreoffice, but if I don't install it, I'd feel something is missing...

#FreeBSD
#tcsh

When you install a new port, but forget to run "rehash":

@FranckPachot @nixcraft @MongoDB How about informing the MongoDB team first and pointing out the problem, rather than twitting about it, which could destroy their volunteer efforts? Have you tried that?

It's an open source project, there's a good chance that the docs may not have been written by the developers.

[Javad Kouhi @j_kouhi]

@netzverweigerer @freebsd_bot Yeah, it's nostalgic, it reminds me of those good old days...

[Javad Kouhi @j_kouhi]

I finally found a decent minimalistic audio player for #FreeBSD: multimedia/audacious

Probably the best alternative to the unmantained, yet legendary xmms.

[Javad Kouhi @j_kouhi]

# rm -rf /
rm: "/" may not be removed

That's how #FreeBSD protects the root filesystem from being wiped out inadvertently, though "/*" still works.

[Javad Kouhi @j_kouhi]

@nixcraft If that's a "Unix" quiz, then probably it should not ask questions about bash, which is not widely used among many Unix operating systems except Linux.

I write all my scripts with /bin/sh, which is the standard shell and every Unix (whatever that means) OS must support it.

[Javad Kouhi @j_kouhi]

Just installed FreeBSD. I've been using OpenBSD for nearly 4 months. But honestly nothing compares FreeBSD, even OpenBSD!
